FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 280,106, dated June 26, 1883.

(No model.)

To all whom it may concern.-

Be it known that I, MILO LUTHER GATES WHEELER, a resident of Oregon City, in the county of Olackamas and State of Oregon, have invented certain new and 'useful Imlowing is a specification.

My invention relates to and is an improvein cut upon Letters Patent No. 253,141, granted.

to me January 31, 1882, for improvements in force-pumps. I

The object of my invention is to simplify in such a'iorcepump the construction and artical section of the suction and pressure cylin-.

ders with bucket and plunger, valves, and tubes in their location. Fig. 2 is an end view of the top of double cylinder, and Fig. 3 is a similar view of the bottom end of double cylinder.

A in Fig. 1 represents the double cylinder,

made all in one piece. B represents the pressure-cylinder, and O is the suction-cylinder. D is the connecting opening or port between cylinders B and G. E is the suction-tube. F is the pressure-tube. G is the valve-seat in cylinder B, and H is the valve. 9 is the opening in valve-seat G toallow the water to pass upward to valve H into tubing F. 'I is the valve located on suction tubing indower part of cylinder 0. J is the double piston, or bucket and plunger in one piece. K represents the water-packing.around the piston J, between packings L L. M is the rod running through piston J, which connects the same to pitman N by joint I.

The cylinder A is held firmly together by iron bands 0 0-one band around each end; and a b are bolts and nuts running through the bands 0 o and cylinder A-one in each end, as shown in Figs. 1 and 2 of drawings.

0 represents in Fig. 2 the top of cylinder A, and d in Fig. 3 represents the bottom of cylinder A. The ends of cylinder A are ehamfered off, as shown in Figs. '2 and 3.

Cylinder O is bored out from end to end of cylinder A, while cylinder B is bored into cylinder A just half way of the entire length. The opening or port D is bored from the bot tom of cylinder Oat the proper angle to allow the operation of boring and connect with cylinder B.

The piston J, or bucket and plunger, is turned out of one piece, the neck connecting the bucket and plunger forming, in connection with the packings L, a water-packing. Q, is the nut on rod M, and holds piston to its-place.

The operation of my invention is as follows:

The pump is primed by filling cylinder 0 with water beforc'inserting piston J. The water enters through port -D and valve H into tube F, and stands at the same height in tube E that it does in cylinder 0. When the cylinder 0 is filled, the piston J is inserted and the air extracted from suction-tube E. Fig. 1 represents the piston J in the act of descent. As piston J descends, the valve I is closed, and the water is forced into cylinder B through port D and valve H, and when the piston ascends on the returnstroke the valve H closes and valve I opens, and the water is drawn up into cylinder 0, and then as the piston J begins the downstroke, the valve I closes and valve H opens, and the same operation of forcing through port D into cylinder B follows. This pump is intended to be used with but one suction and pressure cylinder.

Having described my'invention,what I claim as new, and desire to secure by Letters Patent,- 1s
